Cesium fluoroxysulfate reaction with alkenes

Room-temperature reactions of 1.1-diphenyl-substituted alkenes in dichloromethane with cesium fluoroxysulfate give addition-elimination products, e.g. formation of 1, while the reaction with norbornene gives only 7-fluoronortricyclene and 7-mi-fluoronorbornene.6-7... 

The reaction of alkenes with acetyl hypofluorite436-439 or with fluorine,451-473-474 2,3,4,5,6-pcntachloro-l-fluoropyridinium trifluoromelhanesulfonate ((V-FPCPy-OTf),441-711 cesium fluoroxysulfate,435 (V-fluorobis(triflyl)amine432 or l-(chloromethyl)-4-fluoro-l,4-diaza-bicyclo[2.2.2]octane tetrafluoroborate431 in acetic acid leads to the simultaneous addition of fluorine and the acetoxy group across the double bond. Examples of these additions are summarized in Table 34. Further examples are the formation of l439 and 2 439...
